Mark the coils so you can identify them, try swapping the coils to another cylinder and see if the problem follows the coils to another cylinder or does the cylinder you identify now as missing still have a misfire. If after swapping the coils the cylinder doesn't pick up see if the coil has power and is being triggered by the computer if not the wiring or computer has an issue.
